Abstract (en)
[origin: EP2647969A2] The flow meter (1) has a magnetic field generation device (4) for generating alternating magnetic field passing partially through a measuring conduit (3) perpendicular to longitudinal axis (5) of measuring conduit. Two electrodes (6) are used to measure voltage induced in a flowing medium (2). A supplementary magnetic field generation device (7) is used to generate alternating supplementary magnetic field passing through measuring conduit, in parallel to longitudinal axis of measuring conduit in a region of measuring conduit in which electrodes are located.
